So I went and bought a Radeon HD4890. I first thought that I'd need to buy some kind of molex -> PCI-E cable adapter, but then I realized that my PSU *does* have 2 PCI-E connectors.
Ok, I come home, and start installing the damn thing - until I realize that it has a fucking 8-pin power connector *in addition* to the 6-pin one.
And I don't have a fucking 8-pin connector. WTF do I do?
